BEIRUT, Lebanon, Friday, July 14 — Israel imposed a full naval blockade on Lebanon on Thursday and put Beirut’s international airport out of commission, and the militant group Hezbollah loosed a hail of rockets and mortar shells that killed two Israelis and sent thousands into bomb shelters.

Israeli attacks on Lebanon continued on Thursday. Hezbollah in turn has fired rockets and mortars into Israel. Earlier, Israel entered Gaza’s Kissufim crossing and cut off the southern third of the territory from the rest of the strip.

A day after cross-border raids by Hezbollah fighters brought Israeli troops into Lebanon in force for the first time in six years, Israel sent punishing airstrikes deeper into the country, hitting all three runways at Rafik Hariri International Airport, two Lebanese Army bases. Early on Friday, it struck Hezbollah offices in south Beirut and the main highway between the capital and Damascus, Syria, and later, Reuters reported, a base for pro-Syrian Palestinian guerrillas a few miles from the Syrian border.
